Frequently Asked Questions

What are the main differences between the MP7A1 and MP7A2?

The MP7A2 features a tri-rail system replacing the MP7A1's folding grip for more durable accessory mounting and better zero retention. Additionally, the A2 has a multi-position adjustable stock, unlike the A1's two-position stock.

How does the 4.6x30mm round perform in ballistic gel compared to 5.56mm?

In close-range gel tests, the 4.6x30mm round showed surprising tumbling and expansion, delivering an initial energy dump comparable to 5.56x45mm FMJ rounds.

What is the cyclic rate of the Heckler & Koch MP7A2?

The Heckler & Koch MP7A2 fires the 4.6x30mm round at a cyclic rate of approximately 950 rounds per minute (RPM).

What is the primary design intent of the MP7A2 based on its performance?

The MP7A2's design emphasizes rapid, full-auto engagement. Its high cyclic rate and controllable recoil allow for dumping multiple rounds quickly, compensating for the individual limitations of the smaller 4.6x30mm caliber.
